My SMTP server is running "Post.Office" made by "Software.com". It's been running on a P3-800 mhz computer with 768 mb of ram running Windows NT4 Server since 1998 or 1999. The version of the software dates to either 1999 or 2000. In 2001, Software.com was bought by another company who promptly discontinued the software. The server can run unattended for months at a time without requiring any intervention or maintenance by me. Any mainenance I do is just to add more IP addresses or domain names to the software's SMTP reject/blocking list. > > The issue is the "MAPI1.0" part of the ehlo greeting that my SMTP > > server apparently doesn't like, and it doesn't seem to like it > > because according to SMTP standards "MAPI1.0" is not a valid > > domain-name. > > It isn't? Why not? RFC 2821: (...) > "MAPI1.0" looks like it matches that syntax. Did RFC 2821 exist in 2000 / 2001? I need to check something - there might be a "+" character at the end of "MAPI1.0". Would that change anything?
